Here's the options: Press the 'I' to make it change colour; Press the 'S' to make it spin; Press the 'A' to make it grow and then move for a bit; Press the 'B' to make it move around randomly; Press the 'E' to make it disappear and then reappear; And finally press the 'L' to start the music and also do something else. TIP: Don't press the 'L' while the 'E' is still going because it'll look... weird.
I had so much fun doing this project :)!
